Yeah, right now signal/noise for this statement is huge, because IMO at most 50% of people (likely much less, only the kind of people who are more used to graphs than mountains) who have a good grasp of English but have never heard this expression might get the wrong idea when they hear it for the first time. If we try to invert the meaning it will reduce signal/noise, because the vast majority of people who know the original meaning will now have less information about what you actually mean. We basically have two sensible choices: leave things as is or invent a new phrase which captures the idea even better than the current one.
